Introduction

  • Purpose of our analysis is to understand patterns and correlations of early predictors of (Comorbidities and Etiologies) of cirrhosis’ patients mortality.

  • Cirrhosis is a condition in which the liver is scarred and permanently damaged. A liver that’s affected by cirrhosis is unable to function properly, which causes serious health problems.

Materials - Dataset

Data set used: Early predictors of outcomes of hospitalization for cirrhosis and assessment of the impact of race and ethnicity at safety-net hospitals

<>

Study performed on X patients from 4 safety-net hospitals in the US

Focused in the early predictors of outcomes like comorbidities and etiologies

Methods

Cleaning:

  • Started by extracting necessary columns

  • Adding an ID column as a unique identifier for each observation

  • Renamed columns, reordered them, and assigned classes to etiology and comorbidities.

tidying:

Augmenting:

  • Created categories for Mortality: no death, death in hospital, after 30 days, after 90 days.

  • Creating age bins instead decade

Overview of comorbidities and etiologies

  • Etiology is the study of the factors that come together leading to a disease.

  • Comorbidity is an additional disease that can interact and coexist simultaneously with cirrhosis.
